' balls into such ball-bearings.

According to my invention the outer ring has a cavity or recess of such depth that the i ballscan be inserted in this recess without any resistance up to the ball-race proper,'no inlet recess being necessary in the mner ring, and theinlet is enlarged by a pair of aws v,which engage between the rings and are forced apart by Wedges, screws or the like so that the balls'can pass over the rib or elevation at the recess without meeting any resistance into the center of the ball-race.

One illustrative embodimentof my invention is represented in the accompanying drawing, wherein:

Figure 1 1s a transverse section 111 the central plane in F 1g. 2, Fig. 2 1s a side elevation corresponding to Fig. 1, Fig. 3 is'a plan of the inner ring, outer ring.

In my improved bearing the inlet is arranged only in the outer ring; the inner ring may, if necessary, have a small auxiliary recess in order to' avoid the rings being sprung apart too severely in extreme cases. The

and Fig.- 4 is a plan of the inlet, and, of course, the auxiliary recess,

leave the ball-race proper uninjured. In order that the balls may pass over the ribs which are formed into the ball-race, the rings are so deformed near the inlet by means of an auxiliary device, such as wedges, that the balls can fall without meet- 'ing resistance into the ball-race. \V hen the balls are inserted into the rings the latter receive the necessary mechanical testing,

namely at the weakest place, without the ball-race or the balls being injured in any manner.

. Referring to the drawing, the outer ring 1' is provided with the recess or inlet 2, whilethe inner ring 3 has no'inlet, but only, as mentioned above, a small auxiliary recess 4 for special cases. The recesses terminate a definite distance before the center of the Specification of Letters'latent; Application filed March 23, 1 910.

ball-race and are ribs 5 and G. 2 in the outer ring extends up to the outer edge of ring 1, while the recess 4: never extends up to the edge of ring 3. of the ribs which. remain or the breadth of separated therefrom by the uninjured ball-race is such that the elastic deformations produced when inserting the balls do not exceed the admissible limit.

The recesses 2 and a are such that the balls can 'readily thence into the position II when the rings are concentric. In order that the balls can pass from the position II into the final position III the rings 1 and 3 are sprung so far apart with the aid of special means that the balls can pass freely over the ribs.

The rings are simultaneously tested mechanically and the balls are inserted without either themselves or the ball-race being injured.

One form of my means for springing apart the rings is represented by way of example in the drawing. These means comprise twosi'a wsl and 8 having projections 9 and l0llocated-between the rings and forced so far apart by means of wedges 11, driven inward by a press for example, that balls can pass freely into the ball-race. W hen all the balls have been inserted the stretching means are removed and the rings assume their former shape so that the balls. cannot leave the ball race.

According to my invention the parts of the rings opposite the inlet may be held a definite distance apart in such manner by distance pieces 12, 13 that the balls located there are not loaded by the pressure arising when the ringsv are sprung apart.
